Microeconomics Chapter 1
Scarcity
- All resources are limited, some more than other - have to manage these while fulfilling as many economic wants
- Examples:   * Having to add a minimal amount of armor to fighter jets so they don’t get shot down.   * Increasing minimum wage pays some people more, but also forces businesses to hire less people
- Economists must see possible consequences - can’t just analyze what is there, have to predict what is not
- Scarcity - limited resources, unlimited economic wants
- Capital goods vs. consumer goods   * Capital goods: government spending, more money spent on capital goods -→ future economic growth   * Consumer goods: providing resources to people - helpful to people in short term, but doesn’t encourage long term growth
- Resources: Land, Labor, Capital, and Entrepreneurial ability
- Economics focuses on how to deal with scarcity - macroeconomics deals with entire economy, micro deals with specific markets   * Cannot do economic experiments, way too many variables in the environment; Make assumptions to explain some things
Production Possibilities Curve
- PPC - Used to see the maximum amount of products that can be created with scarce resources
 
- Anything on the line is and efficient use of resources - Inside is inefficient, outside is not attainable   * Model makes assumptions as mentioned before - full employment, fixed resources, fixed technology
- Opportunity Cost - Basically the cost of choosing one option over another   * Example: If you make 10 dollars in a day and decide to go on vacation for 4 days, the opportunity cost is 40 dollars   * Example: Opportunity cost per unit of wood is 5 units of food/20 units of wood: 1/4 unit of food per unit of wood   * Minimal opportunity cost = maximum utility     * Opportunity cost per unit = give up/get     * Opportunity cost of food = reciprocal of opportunity cost of wood: 4 units of wood per unit of food
- Marginal Analysis - Analyzing benefits vs. costs of economic decisions   * MR = MC (Marginal Revenue >= Marginal Cost; Otherwise, Opportunity cost is too high)
- Graph shows constant opportunity cost - As you make more wood, you are losing a fixed amount of food, and vice versa
 
- This graph shows increasing opportunity cost: Basically, as you give up more resources for making one thing to make another thing, those resources are less suited to make the new thing, so the opportunity cost is higher
- Economic Growth = growing the curve so it reaches farther out;   * More resources, or improved resources   * Better Education   * Better technology   * Also possible with international trade
- Some pitfalls in Economics:   * Bias - “First rule of economics → scarcity, first rule of politics → forget rule one of economics.”
